The Second Chamber in the Fourth Act.

ELIZABETH
(entering from a side door; her gait and action expressive
of the most violent uneasiness).
No message yet arrived! What! no one here!
Will evening never come! Stands the sun still
In its ethereal course? I can no more
Remain upon the rack of expectation!
Is it accomplished? Is it not? I shudder
At both events, and do not dare to ask.
My Lord of Leicester comes not,—Burleigh too,
Whom I appointed to fulfil the sentence.
If they have quitted London then 'tis done,
The bolt has left its rest—it cuts the air—
It strikes; has struck already: were my realm
At stake I could not now arrest its course.
Who's there?
